Ellipse Comparison between Color Discrimination Threshold and Small Suprathreshold Color Difference Using CRT Colors
The ellipses of color discrimination threshold and small suprathreshold color difference at the nine CIE Color centers were obtained using the interleaved staircase method and the method of constant stimuli in the a<*>b<*>, a<*>L<*>, and b<*>L<*> planes, respectively. The differences between the threshold and small suprathreshold color difference ellipses were evaluated with respect to their shapes and sizes in terms of PF/3 values. The results indicated that both the shape and size were influenced by their corresponding color regions in the CIELAB color space.
